if a tree falls in the forest and no ones around to hear it, does it make a sound?
no, i havnt lost it, my daughter is trying out for a top school (shes in the accelerated learning program for the gifted and talented) and this was a test question.. i thought it was a crap question, my 10 year old daughter then wrote an essay on it that floored me!
so, come on.. does it?.......

Hahaha, i believe it does we just dont hear it. The fact that no one is around to hear it doesnt change the fact it makes the same sound when it falls as if someone were there to witness it.

any one else got any opinions on the matter???

well, according to the quantum theory the tree may or may not be there. we don't know for sure until we witness the tree there, thereby influencing its what'sitcalled...probability curve (i think)

Well, the tree will create sound waves....which is what we hear....but if nobody hears it....if there is no ear or equipment to actually interpret the sounds waves, then I say no sound is made.
And the quantum theory -- that is so above my head I'm still looking. Guess I have some more reading to do. Posts: 8794 | From: 01-20-09 The End of an Error | Registered: Dec 2004

YES... now, when i studied physics i read the book 'schrodingers cat' which was all about this very subject.. but HELLO!!!! my 10 YEAR OLD daughter is answering essay style questions on this! i never gave it any serious thought at all till she started talking about wave interpretation.. then i stopped what i was doing and sat down!!!!

Tricky question. If the tree falls, the impact causes sound waves, which require sound perceptors to pick up the noise. 'No one' implies human beings, but animals can hear sound too. So, if the tree is not in a vacuum...and there are no animals, birds, humans around, the sound potential would be created but would there would be no one to hear it.

oh.. should have read all the responses before posting.. you are correct. the tree makes no 'sound' only waves. sound only happens in our ears, our ears interpret the waves created by movement. she even went on to explain that if we were standing in front of the tree when it fell, then we travelled at the speed of sound away from the tree, we wouldnt hear the sound it made.
something to think about isnt it?!!!

Depends how you define sound, is it the frequency made? then sound is there whether we hear it or not but if sound is the interpretation of frequency then receptor will have to exist but think about this, what if you're deaf and the sound frequncies are hitting your ear but you don't hear? or what if your ear is abnormal and it interpretate frequncies different from normal ones, will that count? or what if the frequncy is higher -ultrasound- that some animal can hear and some can't, can we say sound exists and not exist at same time?
I think interpretating sound as the frequncy will be less troubing this way we will avoid the contradiction of sound existence , as we can say it exists but not preceived by everyone. Same goes for visible light or IR and UV

hmmm in a second thought I'm finding my explanation problematic too because I'm not making any distinction between sound and light as both are waves and it's only through our receptors that we tell what's sound and what's light but then If I say "NO it doesn't exist" I will be lying because I believe in God who hears and see all.
I'll say move your daughtur to another school Posts: 1539 | Registered: Apr 2006

LOL!!! she spoke about light waves too! i think i have a genius on my hands.. she has been attending high school part time for a while now. she asked me today if i could buy her some GCSE books as she is interested in sitting a few BEFORE she starts high school! the school she wants to go to just got ranked number one in britain.
... and i was planning on home educating her in egypt!!!!

If I fart here in Minnesota, can you hear it or smell it in London Charm? Do you know it exists?
Well if my experience with junior high boy's boxers are any indication of truth, just because I wasn't there to smell it and dealt it doesn't mean it didn't smell. Proof in point lazy stay at home mom won't put bleach in her boy's white laundry, so the skid marks are still there strategically located on their boxers, there is no mistake what happened! If it left a mark then it must have smelt very badly.

That's a standard quote from philosophy text books. An answer could be - what is a sound if it's not heard? I studied philosophy see!
